Key pair authentication is a method of using a public and private key to securely access cloud resources, such as downloading the configuration of assets from a cloud tenancy. Key pair authentication is more secure than user and password or PAM, and does not require an additional factor like MFA.

Timeline analysis in digital forensics involves creating a chronological sequence of events based on system logs, file changes, and other forensic data. This process often uses graphical representations to illustrate and analyze how an incident unfolded over time, making it easier to identify key events and potential indicators of compromise. This approach is highlighted in CompTIA Cybersecurity Analyst (CySA+) practices as crucial for understanding the scope and sequence of a security incident. The other options do not involve chronological or graphical analysis to the extent that timeline analysis does.

Increasing training and awareness for all staff is the best way to address the issue of employees being enticed to assist attackers by visiting specific websites and running downloaded files when prompted by phone calls. This issue is an example of social engineering, which is a technique that exploits human psychology and behavior to manipulate people into performing actions or divulging information that benefit the attackers. Social engineering can take many forms, such as phishing, vishing, baiting, quid pro quo, or impersonation. The best defense against social engineering is to educate and train the staff on how to recognize and avoid common social engineering tactics, such as:

Verifying the identity and legitimacy of the caller or sender before following their instructions or clicking on any links or attachments

Being wary of unsolicited or unexpected requests for information or action, especially if they involve urgency, pressure, or threats

Reporting any suspicious or anomalous activity to the security team or the appropriate authority

Following the organization’s policies and procedures on security awareness and best practices

The correct regular expression to match a GET request to this API endpoint is This pattern checks for the specific URL with an id parameter that accepts integer values. The syntax \d+ matches one or more digits, which aligns with the requirement for a single integer argument. Other options either use incorrect syntax or do not accurately capture the expected URL format. Regular expressions are vital in filtering and identifying patterns in logs, as recommended by CompTIA Cybersecurity Analyst (CySA+) practices for threat hunting and log analysis.
